WINDSHIELD PIVOT.

Application filed April 17, 1922. Serial No. 553,936.

T all whom if may concern.'

Be it known that We, FRANK M. EDGAR and THOMAS P. ARCHER, citizens ot' the United States, residing at Detroit, in the county of lVayne and State of Michigan,

have invented certain new and useful Improvements in Windshield Pivots, of which the following isv a specification.

This invention rela-tes to windshield pivl ots, and has I'or its object a pivot that may be securely anchored on to the windshield frame and which may be easily disengaged from the stanchions. llindshield pivots which are anchored to the swinging panels and which have trunnion portions ruiming l0 better anchorage and through suitable bearings on the stanchions are of course old and common.

Efforts of the inventors must, therefore, be directed to providing pivots which secure which perform the old functions in a better or mo-re eiiicient way. There is opportunity for large improvement in manufacturing efficiency and saving. It is to this end that the pivot here 15 illustrated and claimed is largely direc-ted.

It is made up of parts that can be economically manufactured, either by stamping or by an automatica-l screw machine.

In the drawings:

F ig. l is a front elevation of the windshield.

F ig. 2 is the side elevation of the windshield pivot showing the parts assembled together but the stanchion omitted.

"5 Fig. 3 is a section on line 3k?) of Fig. 2

and including the stanchion.

Fig. 4 is a section on the line 4.-4: of F ig. 2 and including the stanchion.

Fig. 5 is a detail of the trunnion flange.

The stanchion is designated a. A clipb ts around the windshield frame or tube c; this clip is a single stamping. The trunnion (l is secured to this clip b by using a washer e, placing the reduced inner end of the trunnion through the washer and upsetting this reduced end of the trunnion Z to rivet the parts together. This practically locks the clip and washer into one unit, making, however, a very much solider bearing than is the case of the trunnion and clip that are vstamped out of a single piece of metal. At the same time this construction is relatively cheaper from a manufacturing standpoint.

The trunnion d is a screw machine product which may be turned out in great quantities with great rapidity. The outer end of the trunnion is recessed as at It and the stamping or' trunnion fiange z' can be fitted over the end of the trunnion, having pressed in a boss j at the center. rIlhis boss-does not iit the recess tightly and the metal of the flange can be distorted, hence when the iiange is secured to the trunnion bv the screw 7c the metal of the flange can be slightly distorted. Accordingly the stress on'the screw locks the screw from turning loose in the same way a spring washer does. Furthermore, the end of the trunnion is slotted as at m which forms a key-slot for the trunnion iiange lug n. This prevents the flange from turning on the trunnion.

The clip Z) is secured to the windshield frame by screws o that screw into the plug on the inside of the tube. lVhen the screws have been tightened the ends of the screws are upset as g by inserting a tool through the opening 7 in the bottom of the tube channel; this prevents the screws from coming out or loosening.

What we claim is:

l. In a windshield pivot, the combination of a clip in the form of a stamping that may be secured to the panel frame, and a trunnion in the form of a block having a reduced inner end which may be placed through an opening in the stamping and upset to secure the trunnion to the stamping.

In a windshield pivot, the combination of a clip in the form of a stamping, a trunnion in the form of a block having a reduced inner end can be placed through the clip, and a washer fitted over the reduced inner end, the said reduced inner end being upset over the washer to lock the washer and clip together as a unit.

3. In a windshield pivot, the combination of a trunnion in the form of a block having a recessed outer end. a trunnion flange constructed of distortable metal, and a screw securing the trunnion ange to the block and holding the trunnion flange in place `by distorting the metal to lock and screw into its socket.

4. In a windshield pivot, the combination of a trunnion forming a block having a recessed` end and a key-slot in said recess, a trunnion flange comprising a. disk of distortable metal having a boss with a struckout lug and a. screw screwing into ,the trunnion block and having a head engaging in the Harige,

the socket formed by the boss struck out of whereby when the flange and screw are secured luto the trunnion block the lug` engages in the key-slotof the block to lock the `parts against rotation.

n a Windshield pivot, a trunnion provided with a key-slot in its end and having an axial tapped opening, a. trunnion Hang-e provided with a projected lug and a central opening, and a screw passing through said central opening and ruuning'into the tapped opening of the trunnion, whereby when the vscrew is tightened upv the flange may be engaged against the trunnion block and locked in the keysocket against rotation.

6. In a Windshield pivot, the combination oa slotted Windshield tube, a plug secured therein, a trunnion, atrunnion clip secured to the trunniou exteriorly otv the tube, and screws placed through the chp and yscrewing into the plug and having each its' end upset `through an openingin the bottoni of the glass channel ofthe tube.

7. In combination, a slotted Wind shield tube, and means for securing a pivot thereon comprisinga-trunnioma clip secured thereon and arranged exteriorly of the tube, and fastening members passing through the clip and tube having their inner ends clinched Within the tube.
